Interestingly, most comments are talking about the cache/tech capabilities and not the privacy concerns.

I mean the way it was shown is that WebBundles allow the author of that content to arbitrary hide and package content in such a way where you cannot filter specific content; so either you view a page with ads and trackers or you don't see anything at all.

WebBundles can't hide content any more than a regular server can, and blockers can block individual resources from a bundle like they can individual URLs from a server.

but you have to download the whole bundle so you don't get the benefits of blocking at the loading stage, which is quite impactful.

remember that chrome / chromium hamstrung the ability to block at the loading stage; only firefox, ff derivatives and hacked up chromium derivatives can still block prior to loading with complex rules.
